Use of this property is NOT RECOMMENDED, as it is likely to be removed in a later revision.
 
 The rules for serialization of the parameter are specified in one of two ways.
 For simpler scenarios, a [`schema`](#parameterSchema) and [`style`](#parameterStyle) can describe the structure and syntax of the parameter.
